ORTHOIEDIC DEVICE FOR LOOSENING STIFFENEI) SHOULDER JOINT BACKGROUNf) OF THE lNVl-ZN'llON This invention relates to orthopedic devices and particularly to such devices for loosening a shoulder joint stiffened by bursitis. rheumatism. arthritis or the like.
A common affliction of the human body is a shoulder stiffened by bursitis. rheumatism or arthritis. Such a stiffened joint is extremely painful to move but one of the required treatments for such an afliiction is the continued movement of the joint both to prevent further stiffening and to loosen such stiffening as has already resulted from the disease. It is often not possible for the person to move his own shoulder through the normal lift of the arm and some artificial device must be provided for lifting the arm against the stiffness of the joint.
Such devices in the past have been extremely awkward for a person to use without outside assistance and have involved twisting the body in a way that was very painful to the affected joint and often resulted in fur ther difficulties to the patient by twisting or straining other members of the body. Such devices have included wheels and levers requiring the patient to extend the unaffected arm across his body and putting a. twist on the body ofthe patient which strained not only the affected shoulder, but other members of the body.
It is therefor an object of this invention to provide ar-i orthopedic device which a person having a shoulder stiffened by arthritis. bursitis or the like may use with little or no outside assistance and without tlwisting or straining the body to provide a direct lift bit the bumerus against the stiffness of the affected joint.
SUMMARY 'l'hese and other objects of the inventiou'ihave been accomplished by utilizing a bar extending from the affected shoulder to a firm surface. the bar having an opt wardly extending support in the plane of the affected shoulder and arm. and at least one pulley for receiving a flexible member such as a rope interconnecting a sling for uniformly supporting the upper arm adjoining the affected shoulder and extending across the body of the patient to his unaffected arm whereby the patient can effect a lift to his affected arm without movement of the body except by his unaffected arm.
The construction and operation ofthe device will be better understood by reference to the attached drawings in which:
HO. 1 shows the principal members of the orthopedic device of the invention being utilized by a person with a stiffened shoulder;
FIG. 2 is a side view of the orthopedic device of Flt i.
FIG. 3 is a front view. partially cut away. of a second embodiment of the orthopedic device of FIG. I; and
FIG. 4 is a front view. partially cut away. ofthc orthopedic device f FIG. 3 in closed position for storage.
A bar I" which is preferably hollow and of lightweight matcrial such as plastic. extends from the al fected shoulder fthe patient between the joint and the neck to a firm surface I I such as the ceiling. the head of the bed. or a wall. the end l3 ofthe bar 10 contact til ing the affected shoulder is preferably padded. A support 12 extends outwardly from the bar l0 in the plane ofthe torso of the patient and the affected shoulder. At least one pulley or roller I4 is attached to the undersurface I5 ofthc support l2 for guiding a flexible member. such as a rope l6. which interconnects a sling I8 to a handle member 20 to be used by the unaffected arm of the patient. The sling I8 is preferably of soft but strong material and of sufficient width to support the humerus of the entire upper arm adjoining the affected joint. The length ofthe support l2 and the positioning of the pulleys l4 should be such that a direct upward lift is made by the flexible member If) on the upper arm of the patient. The length of the Ilexiblc member 16 should be such as to extend across the body of the patient and to the unaffected arm so that the patient can make a direct pull on the rope without any twist on his body otherwise.
The outwardly extending support l2 preferably is mounted on the bar It) by a hinge 22 so that the support can be pivoted back against the bar It) for storage. A flat pad 24 of resilient, soundabsorbcnt material. such as rubber. maybe attached to the outer end of the bar It) for interaction with the firm surface II.
The bar It) may be hollow. as shown in FIGS. 3 and 4. and the support l2 may be inserted into the hollow member Ill through an opening 26 and hinged to an inner surface of the bar. The pulley or roller I4 is mounted on the undersurface ofthe support l2 and towards its outer end for guiding the flexible member In therethrough. An additional pulley l4 may be utilized toward the inner end of the support II for guiding the rope It), if desired. The llexiblc member It may come down through the hollow body of the member If) and outwardly to the handle 20 to be grasped by the patient.
If the support l2 for the sling I8 is hinged or pivoted to the inside of a hollow member If). the opening 26 should be long enough that the support l2 can be pivoted into the hollow inner area of the bar Ill. The length of the bar Ill may be made adjustable by a tclcscoping member 28 litting inside the outer end of the main frame member MI. The telescoping member 28 may be a stud 32 affixed to one side thereof and extending through a slot 34 in the main frame member 30. The stud 32 should be threaded and interact with a wing nut 36 for holding the telescoping member 28 in properly adjusted length.
The padded member l3 may be arcuate in form for litting over the shoulder of the patient and slidably mounted in the frame member 30 by shaft 38. A quick release nut'dtl. as known in the art. provides for easy adjustment of the position of the padded member 13 with respect to the shoulder of the patient.
l or purposes of storage. the rope to may be pulled outwardly to bring the handle 20 against the base ofthe frame member 30. as shown in FIG. 4. the telescoping member 28 returned to its original position inside the frame member 30 and the support l2 pivoted against an inner wall ofthc frame member 30. The rope I6 and sling ll'l may then be tucked inside the bar member l0 and a door 42 hinged to the frame member 30 closed by a snap lock 44 to provide a device easily stored and handled by the person having the stiffened shoulder.
The orthopedic device of the invention can be used for either shoulder and in a horirontal or vertical position. The device also may be hinged to the head of an orthopedic bed where it can be brought into position for use by a patient in the bed with a minimum of effort.
From the foregoing description, one skilled in the art can easily ascertain the essential characteristics of this invention. and without department from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usages and conditions.
What is claimed is:
I. An orthopedic device for exercising a stiffened shoulder joint by the unaffected arm comprising:
a rigid bar member for extending from the shoulder of the stiffened joint to a firm surface;
a padded member mounted on the inner end of said bar member for resting against said shoulder;
a support member mounted on said bar member substantially orthogonal thereto for extending outwardly in the plane of said shoulder;
pulley means on the surface of said support member for facing said shoulder;
a sling for supporting the upper arm adjacent said stiffened shoulder joint; and
a flexible member attached to said sling and guided through said pulley, said flexible member having sufficient length to be reciprocated through said pulley by the unaffected arm without twist on the unaffected arm or other members of the body, whereby a person having a shoulder joint stiffened by disease may exercise the upper arm in the affected joint by merely moving the unaffected arm.
2. he orthopedic device of claim 1, wherein said support member is pivotally mounted on said bar member.
3. The orthopedic device of claim 1, wherein said sling is of flexible material and of sufficient width to support the upper arm uniformly across its length and wherein said orthopedic device also includes handle means attached to said flexible member for being grasped by said unaffected arm.
4'. The orthopedic device of claim 1, also including a flat resilient member afi'ixed to the outer end of said bar member for interacting with said firm surfacev
